A 'Ihis invention relates to improvements in receptacle closures and hasparticular reference to a cap to be used upon bottles andthe like. l

An important object of the invention is the provision of a cap for milkbottles and similar receptacles formedso as to be conveniently bentoutwardly in segmental form so that only aportion of the bottle may bevAnother Object of theV invention is to provide a cap of the abovecharacter which vmay -be lpartially opened in desirable segyA stillfurtherobject of the invention is Y the provisionfof a cap formed so asto be conveniently crushed inward for removal or partial opening of thecontainer.

Stillanother object of the invention is the provision of-a cap adaptedto enclose a milkbottle or similar receptacle and designed so as to bepartially folded so'as to open' a comparatively small portion of thereceptacle when desirable. v

As is-well known tothose familiar with i the art, Ybottle caps Y arecommonlyY ofrgid1 construction so that when lit is necessaryrto i"5f5.open amilk bottle or other receptacle en- ,fclosed by the sama'theentirecap is neces` ficient to f permit y fanenlarged transversesectionalview taken on the line 3-43 of Fig` for the purpose 45offxillustrationis shown the preferredembodiment of my invention, thenumeral `10 l generally :desivnates `the bottle cap 'structure' of`circularnformation f sarily removed. Thus the contentsof the bottle areexposed to dust and germsto quite a large extent. ticularly to a capdesigned to permit'partial My inventionrelates paropening so that onlyenough of the cap isV raised to per-mit delivery of the contents. IV iththis in'mind, the bottom ofy `my improved cap 10 is provided with aseries of transversely extending grooves 11 prefer-vk ably impressedabout half Waythrough the cap so that a portion of the cap may bereadily turned upward.

lVith particular reference to Figure 2, it Willbe seen that my capis'preferably pro. vided with av pair of central intersecting Grooves 1land 12 and a air of Grooves eX# tending parallel Withone of the centraltransverse-grooves in spaced relation so astor divide the cap VintoV.segments ylessthan one? half thereof. Each vof these segments designedby the numeral 13 isv capable of loeing raised so as to only partiallyuncover the milk bottle or other container but `sufdelivery of the milktherein.

It is evident, from the foregoing, that the cap after being securelymounted inthe milk bottle may be raised by elevation of one of the endSegments equal topractically onees'v fourth of they area ofthe deliveryopeningV or, `if desirable uncovering three-quarters,

It is thus apparent that a bottle oap` of simple yet efticient'designprovided, tendmg to retain milk and similar matter in re vceptacles inmoresanitary condition.
